Limitations for ChemKote 810:

  • Apply ChemKote 810 Primer before applying ChemKote 810.
  • Colors may vary between batches (so use a single batch for a single job) and may be affected by low temperatures and high humidity. Chemical exposure and exposure to sodium vapor lights or similar may also cause discoloration (as it is not UV color stable).
  • Some substrate compositions or chemical contamination can cause surface irregularities in leveling.
  • We recommend a test patch where elevated temperatures are present and chemicals will be mixed or application will be exposed to chemicals.
  • If applying to new concrete, allow concrete to cure for at least 30 days prior.
  • At the time of application, ensure that the substrate temperature is 5°F above dew point.
  • Note that physical properties are given as typical values and are not intended to be specifications.

Application Instructions

Storage Temperature:
Store these products between 60 and 90 degrees F (same as recommended application temperature), keeping it from freezing as the coating may crystalize. Before application, allow product to come to room temperature.

Surface Preparation:
If seeking a thin build (3-10 mils dry, or one or two coats), it is best to employ acid etching or mechanical scarification to produce the appropriate profile. If seeking a thick build in excess of 10 mils dry, it is best to begin with a fine brush blast / shot blast. Ensure the removal of any dust, dirt, oil, laitance, or foreign contaminants. This is essential for optional bonding. To test that the concrete is completely dry before applying the primer (and to reveal if there are any hydrostatic pressure problems at play that may lead to eventual disbanding), tape down all edges of a 4 foot x 4 foot plastic sheet on the substrate. Allow 24 hours to pass and remove the sheet to see if the substrate remained dry beneath.

ChemKote 810 Primer Mixing and Application:
Mix two components together (mix ratio by weight: 9.95# part A to 4.15# part B). After combining, use a jiffer mixer or equivalent slow speed mixer until mixture is streak free. Apply the thoroughly mixed material with a roller or brush (a 3/8” nap roller is ideal). Be sure to not apply the product too thick or allow temperature or humidity to extend beyond the suggested range throughout application and curing.

How to Topcoat the Primer:
Test the primer before adding a coating to ensure the cure is complete and all solvents have evaporated. To do this, press down with your thumb. If no fingerprint is left or dent is created, than the primer has cured sufficiently to recoat or topcoat. (Note that the colder the temperature, the longer the cure time.) Before recoating or topcoating, remove any epoxy blushes (coverage with a greasy whitish film) using a standard detergent cleaner. Note that any existing coats should be deglossed to produce the desired bond.  It is acceptable to apply multiple coats of primer if desired before topcoating.

ChemKote 810 Mixing and Application:
The coating comes in a pre-measured kit and should be mixed accordingly (mix ratio by weight: 10.15# part A to 4.2# part B). Do not break down the kits unless you have access to appropriate weighing equipment. Combine and mix with jiffy mixer or equivalent slow speed mixer until streak free. Once mixed, utilize the separate transfer pail and remix before applying to primed substrate. Note that an effective mix is required for an effective application. Apply the thoroughly mixed material with a roller (1/4” nap roller is ideal), brush, or serrated squeegee (followed by back rolling).  If this last method is chosen, ensure recommended thickness guidelines are followed. Ensure temperature or humidity are not allowed to extend beyond the suggested range throughout application and curing. In the event that air entrapment results from concrete conditions or overly aggressive mixing, utilize an air release roller tool before the roller tacks off. If desired, multiple coats are acceptable and will produce greater build and increased chemical resistance.

Cleanup:
Use xylol to cleanup the primer or coating.

Restrictions:
Allow the floor to cure fully. While the coating is still curing, restrict contact with harsh chemicals and heavy foot traffic.

A Note on Cleaning:
We recommend testing any floor cleaners and cleaning technique in a small area to make sure the floor color is not affected by their use.
